16451 Robinair TruTrack Ultrasonic Sound Generator. An ideal accessory for Robinair’s Model 16455 Ultrasonic Leak Detector, the sound generator detects seal failure in refrigerators, microwaves, vehicle passenger compartments, trunks, and any other location where there should be a good seal.
The 16455 TruTrack™ is an ultra-sensitive leak detector, which uses ultrasound technology to “hear” the sound of a leak. It makes finding a leak fast and accurate because it eliminates annoying false triggering and interference, caused by wind, stray gases or other contaminants
INFICON Whisper Ultrasonic Leak Detector is ideal for detecting and locating sources of ultrasonic sound through the use of sophisticated electronic circuitry. Unaffected by audible noise, Whisper incorporates an Internal Noise Control allowing for use in extremely noisy environments, such as mechanical rooms, and around operating chillers. Whisper Ultrasonic Leak Detector allows the user to check for pressure and vacuum leaks where other sniffer style leak detectors can't go. With the unique internal noise control circuitry, the technician can operate Whisper in high noise environments.
The Whisper Transmitter is an accessory that is used with the Whisper Ultrasonic Leak Detector to locate leaks in walk in coolers, freezers, wall and ceiling joints, around doors, windows, body seals, rubber moldings, and ducts.
Professional digital sound level meter designed to measure noise levels from 35 to 130dB. The unit incorporates a large LCD, maximum hold function, Over and Under range indicator, peak and average response settings and A-C weighing for checking compliance with standard safety regulations. Applications include the monitoring of HVAC/R compressors, blowers, health and safety requirements, environmental quality issues, offices, factory machinery, airports, auditoriums and studio acoustics.
